"Realm of Fear" is the 128th episode of the American science fiction television series Star Trek: The Next Generation.
In this episode, Lieutenant Reginald Barclay (played by Dwight Schultz) has a paralyzing fear of the transporter and is convinced he is being attacked by a creature inside the beam.
[2] Barclay discusses the matter with Counselor Deanna Troi, who teaches him Betazoid meditation techniques to help calm himself.
On his return trip, Barclay believes he sees wormlike creatures in the matter stream that attempt to approach him and touch his arm, but he materializes on the Enterprise without harm.
To remove the microbes, Barclay is put through the transport again, holding him in the matter stream for a longer duration to allow the biofilters to work.
Barclay realizes that the remaining worm creatures in the matter stream are the missing crew members, who are then quickly rescued.
If I lived in the 24th Century, I’d be afraid to transport so I enjoyed exploring some of the deeper neuroses that Barclay had.”[5] The episode was released as part of the Star Trek: The Next Generation season six DVD box set in the United States on December 3, 2002.
